Words and bytes
wordsToBytes :: Num a => DynFlags -> a -> a Source #
Convert the given number of words to a number of bytes.
This function morally has type WordOff -> ByteOff, but uses Num
a to allow for overloading.
bytesToWordsRoundUp :: DynFlags -> ByteOff -> WordOff Source #
First round the given byte count up to a multiple of the machine's word size and then convert the result to words.
roundUpToWords :: DynFlags -> ByteOff -> ByteOff Source #
Round up the given byte count to the next byte count that's a multiple of the machine's word size.

Closure repesentation
A description of the layout of a closure. Corresponds directly to the closure types in includesrtsstorage/ClosureTypes.h.
True = This is a static closure. Affects how we garbage-collect it. Static closure have an extra static link field at the end. Constructors do not have a static variant; see Note [static constructors]
